- 10. WORKING OF LENS The process begins with the delivery of fine metal powder. The powder feed system, controlled by a nozzle or nozzles, directs the flow of material to the deposition area. The substrate or workpiece is prepared, and a thin layer of metal powder is spread over the targeted deposition area.
- 11. WORKING OF LENS The powder feed system deposits a controlled amount of metal powder onto the substrate, forming a thin layer. This layer corresponds to the cross-section of the desired 3D object. The focused laser beam scans or traces the pattern of the intended layer. The energy from the laser causes the powder particles to fuse with each other creating a solidified layer. A Computer Numerical Control (CNC) system controls the movement of the deposition head and adjusts other critical parameters. Steps 3 to 6 are repeated layer by layer, with the CNC-controlled deposition head moving according to the programmed instructions. Each successive layer is melted and solidified on top of the previous layers. The layer-by-layer building process continues until the entire 3D object is fabricated.
